The paper was published Monday in the journal Current Biology and found that bonobo males whose mothers were alive and remained in their group were three times more likely to father children. - Gynecocratic communities -They found that while both bonobo and chimpanzee mothers attempted to assist their sons, bonobos were far more successful because their communities' highest ranks are dominated by females. "The bonobo moms act a bit like social passports," Surbeck told AFP. In addition to intervening in their sons' rivals attempt to mate, bonobo mothers also protected their own sons from the efforts of rivals to disrupt courting and sex. - Grandmother hypothesis -Interestingly, bonobo mothers did not go the extra mile for their daughters, nor did they help their daughters raise offspring.
